These disorders are caused by maturational white matter abnormalities and therefore white matter tractography (using DTI) can offer advantages over conventional MRI in the detectability of clinically relevant microstructural features. High field strength structural MR scanning (up to 7 tesla for clinical and research use in humans) is now available in some countries, and this greatly enhances the spatial resolution over that offered by standard clinical facilities (typically 1.5 or 3 tesla). Similarly, better MRS spectral resolution is achieved at higher field strengths due to improved signal-tonoise and chemical-shift dispersion. The authors describe how developments in MR technology have provided clear clinical and practical benefits but also acknowledge their. | CONTEMPORARY APPROACH TO DENTAL CARIES Edited by Ming-yu Li INTECHWEB.ORG Contemporary Approach to Dental Caries Edited by Ming-yu Li Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution 3.0 license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
